FEEDER FOR DRYING-MACHINES.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed August 30, 1911. Serial No. 646,797.

the type commonly known as a rotary drier,

and one of the objects of the invention is to provide an improved, simple and cheap device of the class described, which will be simple in construction and effective and efficient in operation.

Another object of the invention is to provide means to feed material into the drier and to keep the hopper clean without using a conveyer therefor.

A further object of the invention is to provide means whereby the vapors arising from the drier will be permitted to escape to the charging end simultaneously with the charging operation.

A still further object is to provide improved means for collecting and disposing of moisture formed from the vapor which arises from the material to be dried.

For the attainment of these ends, and the accomplishment of other new and useful objects, as will appear, my invention consists in the features of novelty in the vconstruction, combination and arrangement of the several parts generally shown in the ac companying drawing and described in the specification, but more particularly pointed out in the appended claims.

In the accompanying drawing Figurel is a cross sectional view showing'my invention as applied to the charging end of a rotary drier. Fig. 2 is an end view of the same showing the preferred form of the blades of the charging device in dotted outline.

Some difliculty is'experienced in'feeding materials such as grains and the like to a drier in such a manner that the vapors arising therefrom may escape to the charging end, and in collecting and disposing of the moisture contained in the vapor as it es- In feeding material to be dried it may be desiredto mix the materials incertain proportions, and it is not always convenient to measure the materials as they are placed in the mixing hopper. This invention is designed to overcome these difficulties, and to provide a simple, cheap and eflicient device of the class described.

Referring now more particularly to the drawing, a portion of a drier 10 of a type commonly known as a rotary drier, is shown, having a topped ring 11 secured thereto, which meshes with the gear 12 and the driving shaft 13. At the end of the drier shown is located the charging device, which comprises a mixing hopper 14:, m which 1s located a charging device 15. This charging approximately fit the curvature thereof, so

that material discharged into the mixing hopper is thereafter discharged into the drier by the operation of the charging device 15. a

Extending upwardly from the mixing hopper let is a vapor'stack 20, formed with enlarged-portion 21, with a lower beveled portion 22, which extends to the top of the vapor stack 20 and forms a receptacle 23 around the top of the vapor stack. A discharge pipe Qi is connected with the receptacle 23, and is adapted to convey fluid from the said receptacle. In the upper part of the enlarged portion 21 is a deflector plate 25, supported by ribs 26 and extending over the vapor stack 20. This deflector plate or cap 25 is preferably beveled in shape and is adapted to direct moisture formed from the vapor or descending from other parts of the vapor stack from dropping into the vapor stack 20. The moisture asit forms from the vaporon the sides or walls of :the vapor stack runs down the sides and is collected in the receptacle 23 about the upper portion of the stack 20, from-which it may be discharged in any desired or suitable place, This device in 55 revoluble blade positively to charge material; to be dried Within the drier at the end. thereof, said blade being formed with r spaced sections to permit. the egress of construction PIGXGIltS the moisture formed from the vapor from dropping through the vapor stack 20 and into the mixing hopper 1%, thereby obviating thecontinuousvaporlzation and congealing of the vapor.

Extending from the end of the hopper 14 i p and communicating therewith is, a charging hopper 27 in which a conveyer 27 preferably of. the spiral type is rotatable, the lat-' ter having driving connection with shaft 18. A charging hopper 28 may 'also'eXtend from the side of the hopper 14, With a spiral conveyer 8O rotatable "therein and preferablyzsituated on the same shaft 16 as the charging device 15.. Either one of the charging hoppers may be used alone or omitted,or may be operated simultaneously. In thelatter event it is evident that thesaid hoppersmay be employed to feed materials ofathe same or different kinds to the hopper let in any desired or suitable proportions.

Suitabl drivin'g means are provided for driving the shaft 16 and the conveyer 29, and it is contemplated-that-the speeds at which theconveyers-are driven. may be varied in any desired manner, so that the charging hopper Vmay be supplied with a mixture of any desired proportions. It is evident that the charginghopper may be as large as is ,desired but that the rate at Whichthe-mat'erial therefrom is discharged depends-entirely upon therate at Which the conveyer is operated. I I

It Will be, seen thatthe-charging device 15 substantially fills the bottom of the hop- 7 per 14,50 that the-rotation of the device This is. accomkeeps the hopper clean. plished Without the useof la ,conveyer in the hopper, atthesameitime permittingthe escape of vapors atthe charging end.

- It will he -noted that the vapor'ispermitted to escape through the blades of the chargingdevi'ce .15 in a direction opposite to thatin-Which the. material to be dried is supplied to the drier, and that'the passage" of the vapors is'in-no Way obstructed by the ,material discharged in the drier.

VVhi1e I have thus described the preferred construction, combination and arrangement of, (the several parts Which constitute my qinven-tion, it is evident that others may ;make various changes Without departing from the spirit and scope of. the invention.
